Operation
Startup Procedure
1. Engage the Emergency Stop button.
2. Set on the main power switch to “On”.
Light Tower Operation
Three stacked indicator lights and a buzzer are used to show the status of the machine. The
lights are green, amber, and red with the buzzer below the green light. The lights are visible
from all sides of the machine. The indicators operate as follows:
State
Red
Amber
Green
Buzzer
Cycle Stop
ON
OFF
OFF
OFF
Auto Cycle OFF OFF ON OFF
Cycle Stop OFF ON OFF OFF
Auto Cycle Standby OFF ON OFF OFF
Machine Error OFF OFF OFF Buzz

Shutdown Procedure
1. Wait for all boards to clear the module. The machine should be shutdown with no
parts in the module.
2. Set the main power switch to “Off”.
Caution: If maintenance will be done during the shutdown, lockout and tag the
machine.
Cycle Stop
Cycle stop state is the default state for the PVA Queue/Inspection module. Cycle stop occurs
when the Emergency Stop button is engaged and there is no fault. The red light will be on in
cycle stop. The machine will not cycle boards in this state. To enter auto cycle, disengage
the Emergency Stop button.

Auto Cycle
Auto cycle is the normal operating mode and occurs when the Emergency Stop button is
disengaged and there is no fault. The module operates as part of a larger production line and
automatically communicates with adjacent machines. The amber light is on when the
module is waiting for a board, the green light is on when the module has a board.
Note: The PVA Queue/Inspection module can carry one board per conveyor section.
More than one board per conveyor section will cause trafficking problems.
Queue Module
When the queue module operates as a transfer station, auto cycle operates as follows:
1. The queue module sends a ready signal to the upstream process that it can accept a
board.
2. A signal from the upstream process that a board is available or a signal from the
upstream sensor starts the conveyor. If there is no upstream process the board will
be manually loaded.
3. When the upstream sensor is triggered, the ready signal to the upstream process (if
present) is stopped.
4. The board moves to the downstream sensor unless the Emergency Stop button is
engaged.
5. A signal is sent to the downstream process (if present) that a board available.
6. If the downstream machine is ready, the board will move out of the queue module.
7. If the downstream machine is not ready, the board will stop on the downstream
sensor until a ready signal is received, or the board is removed.
8. When the downstream sensor is clear, the board available signal to the downstream
process (if present) is turned off.
9. The cycle then starts again.

Inspection Module
When the inspection module operates as an inspection/transfer station, auto cycle operates
as follows:
1. The inspection module sends a ready signal to the upstream process that it can
accept a board.
2. A signal from the upstream process that a board is available or a signal from the
upstream sensor starts the conveyor.
3. If there is no upstream process the board will be manually loaded.
4. When the upstream sensor is triggered, the ready signal to the upstream process (if
present) is stopped.
5. If the Bypass switch is off, the board will move to the inspection sensor and stop.
6. Remove the board for inspection or leave it on the conveyor.
7. After inspection is complete, push the continue button.
8. The board shuttles to the downstream sensor unless the Emergency Stop button is
engaged.
9. A signal is sent to the downstream process (if present) that a board is available.
10. If the downstream process is ready, the board will move out of the inspection module.
11. If the downstream process is not ready the board will stop on the downstream sensor
until a ready signal is received, or the board is removed.
12. When the downstream sensor is cleared, the board available signal to the downstream
process (if present) is stopped.
13. The cycle then starts again.
